Pleased to see that London's experiment with reducing street clutter in High Street Kensington has improved safety, consistent with our own "less is more" philosophy of managing safety.
Two years ago part of Ken High St was revamped, with pedestrian guard rails removed, many traffic signs removed, etc. Accidents involving pedestrians have dropped by a whopping 40-odd% since the changes.
(Reported in today's Evening Standard, but can't find it on their site. Similar, but apparently older, stats are reported here, though.)
